England, coached by Mark Mapletoft, have reached the tournament's two previous finals and go to South America in June 2010 looking to claim a first global title.

They are based in Rosario for the three pool games, starting against the host nation on Saturday, June 5. They take on Ireland on June 9 and fifth seeds France on June 13. The fourth round and finals day are on June 17 and 21.

This year England beat Japan 43-0, Scotland 30-7, Samoa 52-7 and South Africa 40-21 in Tokyo before losing 44-28 to New Zealand in the JWC final.

"Playing the host nation Argentina in the opening game next summer will be a great occasion," said Mapletoft, who won his only England cap in Buenos Aires in 1997.

"We had that experience against Japan this year in Tokyo when the atmosphere was brilliant and the welcome we got made it extra special.

"Argentina are now a major nation on the world stage at senior level and that will filter down to their Under 20 side.

"The other games will be intriguing as we'll already have faced Ireland and France. By the end of the RBS Under 20 Six Nations in March we'll have a clear idea of our chances of progressing through the group stages in Argentina."

Next year's tournament is in a new 12-team format with the three pool winners and the best-ranked runner-up playing in the tournament semi finals on June 17 in Rosario, where the final and bronze medal matches will be staged on June 21.

England start their preparations for the campaign with two days at Twickenham this month and training camps in December and January before kicking off the Six Nations against Wales on February 5.

Mapletoft can call on 16 players capped at Under 20 level last season, including seven who took part in the JWC in Tokyo
